Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker testing, in particular to a testing device for loudspeaker production. Background Art

[0002] Speakers are commonly known as "horns". They are a very commonly used electroacoustic transducer and can be found in all electronic and electrical equipment that make sound. During the production process, speakers usually need to be tested for sealing. At this time, an airtightness tester is needed. Workers put the speakers on the test bench seat of the airtightness tester, and then the sealing block above the test bench presses the speakers on the test bench seat to pressurize the gas, and the airtightness test is performed based on the change in gas pressure.

[0003] At present, when the airtightness tester is performing ventilation testing on the sealed block at the socket of its own testing bench, the socket of the testing bench usually needs to be tightly clamped on the speaker shell. When the worker manually takes the speaker for testing, some external impurities are likely to fall into the socket, resulting in the socket being unable to be tightly clamped into the speaker shell. When the worker manually cleans the impurities in the socket, it is easy to bring in other impurities in the palm of the hand, thereby affecting the continuous testing efficiency of the speaker at the socket of the testing bench. For this reason, we propose a testing device for speaker production. Utility Model Content
